Local anaesthetic can be injected around the nerve for skin grafts and surgery around the outer thigh.

[3] It crosses the iliacus muscle obliquely, toward the anterior superior iliac spine (ASIS).

It divides into branches which are distributed to the skin of the anterior and lateral parts of the thigh, as far down as the knee.

It subdivides into filaments, which pass backward across the lateral and posterior surfaces of the thigh.

[3] The nerve is easier to see over the sartorius muscle than in other subcutaneous tissue, as there is greater contrast.

[1] The lateral cutaneous nerve of the thigh can be blocked with local anaesthetic.

[3] In patients who only have meralgia paraesthetica on one side, ultrasound scans are performed on both thighs to compare the appearance of the nerve.
